ATCO Emissions Management (ATCO) announced the addition of heat recovery steam generators (HRSGs) to its line of gas turbine auxiliary equipment for the power, oil, gas, and cogeneration markets. The new HRSG product, an energy recovery heat exchanger that recovers heat from a hot gas stream, will initially serve facilities with gas turbines up to […]

Feedwater heaters are used to preheat boiler feedwater by condensing steam extracted from several stages of the steam turbine. Feedwater heaters enhance the thermal efficiency of the power plant by reducing the amount of fuel burned in the boiler to produce a specified power. At the same time, the steam energy extracted from the turbine by the feedwater heater helps to reduce the rate of energy rejection to the environment via the condenser.

Most professionals in the energy industry know about biomass; fewer of us are conversant with biogas. This commentary explains the basics of biogas, with a focus on its current use and future potential as a source of electrical power.

Japan’s scramble to replace generation lost from nuclear power plants that were shuttered after the March 2011 Fukushima Daiichi nuclear accident has forced it to rely on pricey imports of fossil fuels—and soaring energy costs are hammering the world’s third-largest economy.

More and more electricity is generated by natural gas. This trend is likely to persist. Hydraulic fracturing technology is increasing domestic supplies and enabling natural gas prices to remain at historic lows.

A pervasive drought in northeast Brazil has dried up power supplies from the region’s hydropower facilities, making the area prone to blackouts and crippling economic growth in one of the country’s emerging agricultural havens.

The use of low-grade coal is becoming synonymous with circulating fluidized bed (CFB) power plants. Although CFB technology may often be a better choice than pulverized coal technology, that is not always the case. Owners and developers need to consider several technical and economic factors before making this decision.

Selected business news and deals in the power generation industry.

Covanta Energy and the City and County of Honolulu recently completed a $300 million expansion of a 20-year-old waste-to-energy (WTE) facility. The plant is now capable of processing up to 3,000 tons of municipal refuse daily, recycling all the metals, and generating up to 90 MW—enough to supply nearly 10% of Oahu’s electricity.

As the book title Too Dumb to Meter: Follies, Fiascoes, Dead Ends, and Duds on the U.S. Road to Atomic Energy implies, nuclear power has traveled a rough road. In this POWER exclusive, we present the 16th and 17th chapters, “Uranium Rush and the New ’49ers” and “Naked Shorts at Westinghouse,” the first two chapters of the “False Scarcity and Fools for Fuels” section.
